X6 16GB (ORI) said to be priced around RM1.4K
Better get the 32GB edition.Cost extra RM200 but + free music & extra space.

I had a Nokia N900 AP Set (AP Company : Asia Pacific Mobile)
Used it for around 18 months without any issue (even though I hacked it inside out)

The reason why I bought AP set for this phone was because the price difference.When N900 was 1st launched it's price was around RM2.3K.AP set was RM500 lower.

Just switched for Samsung Galaxy S II SME set.This time I got the ori because the price difference between ori & ap is just RM100+ and as a bonus mine comes with 2 years warranty.

I'll advise those who are in tight budget to take AP set.You can also consider taking the AP set if the price difference between AP & ori set is too much.But most of the smartphone's price with the exception of LG Optimus 2X are almost the same +/- RM100 only.Do your research before buying a AP set.There are some decent AP company like CSL.
If you have extra budget & want peace of mind go for ori set.Do remember for smartphones nowdays it's internal is similar to laptop.Quite complex & some problem need trained personnel to fix it.Pay extra to get the best possible care for your device if it went nuts.
